What do I do with extra wire in light fixture?

Quote from the video:
Quote from Youtube video: You get the other one put two back together you want to make sure that those caps are on your wires. So that way somebody doesn't get electrocuted.

What is the third wire on a light fixture?





The third copper colored wire is the ground wire. Twist the exposed parts of the white wires together clockwise, then screw the wire nut onto the ends.

What is the extra copper wire in light fixture?

It is a frame ground. It’s bonded to the metal of the fixture so that if a bare live wire touches the metal it trips the breaker.

What do you do with the extra hot wire?

The live wire may have been installed for a future closet light. Safe Keeping for Spare Electrical Wires and Cables You may also reroute the wire into another electrical box and just cap off the wires. The other alternative is to trace the wire back to its origin and totally remove it.

Why do I have 2 black wires and 2 white wires?

So, why are there two black and two white wires in your outlet box? There are two black and two white wires in an outlet box because the outlet is in the middle of a series circuit, accepting power from another source and sending it on. Two cables are hot wires, bringing the power in and carrying it onward to the next.

Can you cap off a live wire?





Quote from the video:
Quote from Youtube video: So if you take a look at this electric at these electrical wires right here you'll notice that there are three wires. There is a white one which is the neutral a black one which is the hot wire or the

What is the third wire for?

Three-conductor wire has two hots — black and red — and a white neutral. Though normally used for three-way switching, three-conductor wire is commonly used for duplex receptacle wiring as well. For a partially switched receptacle, for example, you would break off the tab on the brass side of the receptacle.

What is the 3rd wire?

Definition of three-wire system



: a constant potential system of electric distribution in which lamps or other receiving devices are connected between either one of two main conductors and a third wire and motors and heavy duty appliances are usually connected across the main conductors.

Why does my ceiling light have 3 white wires?

The black wire is the hot wire, the white wires are neutral and ground is ground. You need to connect the black wire of your light fixture to the black ceiling wire, the white wire fixture to the 3 white wires, and the ground wire to the ground wire.

What is a secondary hot wire?



Red wires are usually used as secondary hot wires. Red wires are also hot and should be clearly marked to avoid the dangers of electrocution. Red wires are commonly used when installing ceiling fans, where the light switch maybe.

Why would there be two hot wires?

The reason for multiple hot/neutral wires for one outlet is that the outlets are daisy-chained together. This means hot/neutral is only coming from one of the wires and it is being sent to the other wire.

What happens if you connect 2 hot wires?

Two hots of same circuit – nothing should happen.

Is pigtail wiring safe?



Pigtailing aluminum wiring is safe as long as proper terminals and connections are made – without damaging the wire – and with materials approved by the Canadian Electrical Code. Aluminum wiring pigtails approved by the Electrical Safety Authority are the most common solution for making aluminum wiring safe.

Why are both white and black wires hot?

The black wire is the “hot” wire, it carries the electricity from the breaker panel into the switch or light source. The white wire is the “neutral” wire, it takes any unused electricity and current and sends it back to the breaker panel.

How do you wire a light fixture with two sets of wires?

Connect the lead wires from the fixture to the black hot wire in the electrical box by twisting a wire connector to the ends of the lead and hot wires. Repeat these connections with the two white neutral wires from the light fixture and the white neutral wire in the light fixture box.

Why does my ceiling light have 4 wires?

In order for the light to be controlled by its own switch, the wiring between the switch and the fan unit needs a fourth wire, a red wire, to carry power to the light kit.

What happens if you connect the wrong wires on a light fixture?



But here’s the catch: If you connect the circuit wires to the wrong terminals on an outlet, the outlet will still work, but the polarity will be backward. When this happens, a lamp, for example, will have its bulb socket sleeve energized rather than the little tab inside the socket.

What does the red wire connect to in a light fixture?

Normally you’ll see a red wire in places you would expect a ceiling fan. But in places like a bathroom or a wall light, if you see a red wire, it’s a good bet that the red wire is the wire that’s connected to the light switch.

Can I put the red and black wires together?

These wires are typically used for switch wiring as well as the interconnection between smoke detectors hard-wired into the power system. You can link two red wires together, or you can link a red wire to a black wire. Since red wires conduct current, they are considered hot.

Can red and white wires go together?

In the US, the answer would be no, even though I am reluctant to answer this. White is not aggressive. White is neutral, black is 120, green is ground, and red is the other phase of the mains into your house.
